    Aquaculture Operations in Floating HDPE Cages: a field handbook 2015
    Also available in:

    Cage aquaculture has grown rapidly during the past decades and there has been a move towards the development and use of more intensive cage-farming systems to access and expand into untapped open water areas, particularly in marine offshore waters. Fish cages vary in design, size and material used as they have been designed for employment in diverse environments, ranging from relatively protected to highly exposed and dynamic sites, either as floating or fully submerged structures. This technica l manual focuses on the high density polyethylene (HDPE) cages as they are widely used in modern-industrial marine aquaculture in many parts of the world. It provides the reader with highly practical and technical information on the design and components of a typical HDPE cage, on how a cage collar is assembled and the net pen installed. Along with the structure of the cage, comprehensive information on the grid mooring system and installation is provided. Finally, information on farming operati ons that includes maintenance and control of the farming structures, stocking of the farmed fish, feeding, harvesting and packaging are discussed along with other practical aspects and routine management operations.

    Capture-based aquaculture. Global overview. 2008
    Also available in:

    Aquaculture is a diverse and multibillion dollar economic sector that uses various strategies for fish production. The harvesting of wild individuals from very early stages in the life cycle to large mature adults for on-growing under confined and controlled conditions is one of these strategies. This system, referred to as capture-based aquaculture, is practised throughout the world using a variety of marine and freshwater species with important environmental, social and economic implications. The need to evaluate the sustainability of this farming practice in light of its economic viability, the wise use of natural resources and socio-environmental impacts as a whole has been extensively discussed at national, regional and international levels. In 2004, the Food and Agriculture Organization of the United Nations (FAO) launched a project entitled “Towards sustainable aquaculture – selected issues and guidelines” funded by the Government of Japan which included a thematic component o n the use of wild fish and fishery resources for aquaculture production. The objective is to produce a set of technical guidelines that would assist policy-makers in developing informed and appropriate capture-based aquaculture regulations that would take into account the use and conservation of the aquatic resources exploited. This publication contains technical information prepared in support of and background material for the “FAO international workshop on technical guidelines for the respo nsible use of wild fish and fishery resources for capture-based aquaculture production” held in Viet Nam in October 2007. The first draft of the technical guidelines on capture-based aquaculture was produced during this meeting. This publication contains two parts. Part 1 consists of two reviews on (a) environmental and biodiversity and (b) social and economic impacts of capture-based aquaculture and Part 2 consists of eleven species review papers. Both marine and freshwater examples have been r eviewed and include finfish (mullet, bluefin tuna, European eel, cod, grouper, yellowtail, Clarias catfish, Indian major carps, and snakehead and Pangasiid catfish), crustaceans (mud crab) and molluscs (oyster).

    The Aquaculture and Inland Fisheries Project, (AIFP) otherwise known as AnnexII of the Nigerian Special Programme for Food Security (NSPFS) was operational between 18 July 2003 and 30 June 2006 for 35 months. The AIFP’s objectives included compiling an inventory and data base of inland water bodies, fish farms and feed mills, providing technical assistance to private fish farmers and assisting artisanal fisherman in community-based management of inland waters. A good linkage was forged between p rivate fish hatcheries and the stocking of lakes for increased fish production. Efforts were also made towards reduction of post harvest loss of fish through improved fish smoking demonstrations. The project was successful in creating increased public awareness on aquaculture and fisheries bringing them to become national development priorities.

    Emissions due to agriculture
    Global, regional and country trends 2000–2018
    2021
    Also available in:
    No results found.

    The FAOSTAT emissions database is composed of several data domains covering the categories of the IPCC Agriculture, Forestry and Other Land Use (AFOLU) sector of the national GHG inventory. Energy use in agriculture is additionally included as relevant to emissions from agriculture as an economic production sector under the ISIC A statistical classification, though recognizing that, in terms of IPCC, they are instead part of the Energy sector of the national GHG inventory. FAO emissions estimates are available over the period 1961–2018 for agriculture production processes from crop and livestock activities. Land use emissions and removals are generally available only for the period 1990–2019. This analytical brief focuses on overall trends over the period 2000–2018.

    The State of Food Security and Nutrition in the World 2021
    Transforming food systems for food security, improved nutrition and affordable healthy diets for all
    2021
    In recent years, several major drivers have put the world off track to ending world hunger and malnutrition in all its forms by 2030. The challenges have grown with the COVID-19 pandemic and related containment measures. This report presents the first global assessment of food insecurity and malnutrition for 2020 and offers some indication of what hunger might look like by 2030 in a scenario further complicated by the enduring effects of the COVID-19 pandemic. It also includes new estimates of the cost and affordability of healthy diets, which provide an important link between the food security and nutrition indicators and the analysis of their trends. Altogether, the report highlights the need for a deeper reflection on how to better address the global food security and nutrition situation.To understand how hunger and malnutrition have reached these critical levels, this report draws on the analyses of the past four editions, which have produced a vast, evidence-based body of knowledge of the major drivers behind the recent changes in food security and nutrition. These drivers, which are increasing in frequency and intensity, include conflicts, climate variability and extremes, and economic slowdowns and downturns – all exacerbated by the underlying causes of poverty and very high and persistent levels of inequality. In addition, millions of people around the world suffer from food insecurity and different forms of malnutrition because they cannot afford the cost of healthy diets. From a synthesized understanding of this knowledge, updates and additional analyses are generated to create a holistic view of the combined effects of these drivers, both on each other and on food systems, and how they negatively affect food security and nutrition around the world.In turn, the evidence informs an in-depth look at how to move from silo solutions to integrated food systems solutions. In this regard, the report proposes transformative pathways that specifically address the challenges posed by the major drivers, also highlighting the types of policy and investment portfolios required to transform food systems for food security, improved nutrition, and affordable healthy diets for all. The report observes that, while the pandemic has caused major setbacks, there is much to be learned from the vulnerabilities and inequalities it has laid bare. If taken to heart, these new insights and wisdom can help get the world back on track towards the goal of ending hunger, food insecurity, and malnutrition in all its forms.
